SPIRAL WOUND GASKETS
Specially designed for high-pressure applications and temperatures over 550°C, spiral wound gaskets can balance changes in temperature and pressure and ensure a secure seal.
SPIRAL WOUND GASKET SPECIFICATIONS
Spiral wound gasket specifications are very flexible. They can be tailor-made to suit the requirements of the application by combining different winding materials and metals.
Spiral wound gaskets are semi-metallic gaskets composed of two components: a soft gasket filler and a metal strip. These are wound together so that there are alternating layers of gasket filler material and metal. The filler material is the main seal, while the metal ensures that the gasket retains its shape and provides structural strength.
The materials selected for the metal strip are determined by the needs of the application in terms of fluid corrosion, operating temperature, pressure, and other factors. The most commonly used material is Stainless Steel 304, 316, and 321.
The filler material is most commonly graphite, ceramic paper, mica, and asbestos. While most often round in shape, spiral wound gasket manufacturers can make them in rectangular, oval, or diamond shapes.
BENEFITS OF SPIRAL
WOUND GASKETS
Spiral wound gaskets could be the right solution for your application. Some benefits include:
- They play a role in padding, sealing, leak prevention, mounting, protecting against contaminants, and reducing or minimizing vibration
- Work well under high-pressure, high-temperature, and corrosive environments
- Require less clamping than solid gaskets
- Due to their profile which resembles a chevron, they provide spring-like padding making them suitable for many different work environments
- Reliable and strong, able to prevent gear failure and the following unexpected and expensive downtime
- The outer metal ring simplifies assembly and prevents blow-out
- The inner ring prevents the radial flow of soft filters and reduces turbulence, and so minimizes flow resistance
- The center ring provides extra strength to prevent blow-out, overloading, and over-compression of the gasket
SPIRAL WOUND GASKET APPLICATIONS
The original spiral wound gasket application was to meet the demanding conditions of oil refinery operations in the early 20th century. They are still used today in the oil, gas, and petrochemical industries due to their ability to cope with high pressures, extreme temperatures, and chemical attack.
Spiral wound gaskets are used in any industry that has a need for gaskets to be placed in pumps and pipes, valves, heat exchangers, and other equipment. Such industries include:
- Gas and petrochemical
- Chemical production
- Power generation
- Metallurgy
- Shipbuilding
- Any industry with high pressure and high-temperature applications
